Attempting to print preview the URL provided results in Preview displaying "File error.", "Couldn't open the file.". A quick look through the PDF that is generated shows it looks roughly like a PDF document, so the contents of it are likely to be the issue.

This is the log I see:
Warning: The printing graphics context is being released by the printing system but is retained by the drawing client. This usually produces damaged PDF documents!
I expect this is due to KCanvasRenderingDeviceContextQuartz.
I also see the whole SVG repainting itself twice during the print, which surprises me.

re #4
Eric this is almost certainly not fixed. as well as the URI above I checked a simple SVG: http://bugzilla.opendarwin.org/attachment.cgi?id=8239
in both cases print preview dialogue: "file error couldn't open the file OK"
and trying again later opened a blank pdf document

eric, macdome please explain why this is fixed?
the latest nightly is not printing either of the svgs in the 2 URIs given
10383 is not showing as fixed, yet this bug is apparently dependent on it...
cheers
